Product Details

The English cucumber is longer (up to 18") and thinner than traditional cucumbers, with very small, soft seeds. 'Telegraph Improved' was developed in the 1800s for growing in greenhouses, but is now a favorite of home gardeners for the long, thin-skinned, burpless fruits that add a cool, mild flavor and a snappy crunch to salads and sandwiches. Cucumbers develop best when grown on a trellis and get regular moisture while fruits are forming.

Growing Info

Harvesting: Pick, and pick some more! Overly mature cucumbers on the vine will slow production of new cucumbers. Cut the stem rather than pulling at the fruit, as stems are fragile. To increase the quality and storage time, once picked, immediately immerse in cold water to disperse "field heat".
